"Canonbury"

My post a couple weeks ago about Haydn's tune "Austria" reminded me of an-other instance where a classical piece is used a hymn tune.  "Canonbury" (used for LSB #551 "When to Our World the Savior Came") is adapted from the fourth of Robert Schumann's Nachtstücke, Op. 23.  Incidentally, Schumann's birthday is next week; he was born on 8 June 1810.
